The following example enables BFD for specific static routes on a nondefault VRF:
OS10(config)#ip route vrf LAN2 10.2.2.0/24 10.1.1.1 bfd
The following example enables BFD for specific IPv6 static routes on the default VRF:
OS10(config)# ipv6 route 2111:dddd:0eee::22/128 2001:db86:0fff::2 bfd
The following example enables BFD for specific IPv6 static routes on a nondefault VRF:
OS10(config)# ipv6 route vrf LAN2 2111:dddd:0eee::22/128 2001:db86:0fff::2 bfd
Change the BFD session parameters for static routes
To change BFD session parameters for IPv4 or IPv6 static routes, use the following command in CONFIGURATION mode:
bfd interval milliseconds min_rx milliseconds multiplier number role {active | passive}
The following example changes the BFD session parameters for static routes:
OS10(config)# bfd interval 250 min_rx 300 multiplier 4 role passive
Disabling BFD for IPv6 Static Routes
To disable BFD for IPv6 static routes, use the following command.
Disable BFD for static routes.
no ipv6 route bfd
CONFIGURATION Mode
BFD commands
bfd
Enables BFD sessions with specified neighbors.
Syntax
bfd
Parameters None
Default Not configured
Command Mode
ROUTER-NEIGHBOR
ROUTER-TEMPLATE
Usage
Information
Use the bfd command to configure BFD sessions with a specified neighbor or neighbors which
inherit a BGP template. Use the neighbor {ip-address | ipv6-address} command in
ROUTER-BGP mode to specify the neighbor. Use the template template-name command in
ROUTER-BGP mode to specify a BGP template. Use the no bfd command in ROUTER-NEIGHBOR
mode to disable BFD sessions with a neighbor.
Use the bfd all-neighbors command to configure L3 protocol-specific BFD parameters for all
BFD sessions between discovered neighbors. The BFD parameters you configure override the global
session parameters configured with the bfd interval command.
Example
OS10(conf)# router bgp 1
OS10(config-router-bgp-1)# neighbor 10.1.1.1
